HelloAfter researching on this forum for years every time my car has problems, im finally stumped and have to actually ask as i cant locate a solution here! Any advice HELPS! Quick background, I was given this GP seven years ago and up until last year, i had a live in mechanic. We broke up,now im screwed when something goes wrong! Car just hit 200K last week. I live in FL where it gets flooded pretty often. Last night i was attempting to get to my moms when the rain let up. The roads had standing water in some parts, but other cars where going just fine. I started going through the first large area of water, about a foot or less deep. I kept under 10 mph. Everything was fine. Next body of water, i did the same thing, but right towards the end, i felt the damn belt come off. All the signs, dimmed int lights, no power steering, etc. Well i babied it home,as i was only about half a mile away luckily. The belt does this often when i have to go through rain,even though the pulley is brand new? Anyhow, got it home, let it dry in garage for a few hours, then put belt back on. Left it in the driveway over night. Got in it this morning noticed my check engine light was on,and started on my way to the store (as i got screwed on din din the night before!) Got maybe half a mile, go to slow down to turn, and car SHUTS OFF! No warning,nothing. All lights inside stayed on, obviously not a battery issue. So i checked the belt, not it. It cranked right back up and i headed for home. It shut off and cranked back up almost four times before i made it home.
So i got it in the garage ans started checking things. I took the MAP sensor off and let it run, it idled BAD and and when i pressed the gas,then slowly let off, it shuts off. So i tried with the MAF sensor too, same! So where im at right now, the car sounds pretty bad while idling, but isint dying when left alone. Give it a little gas in park, and as soon as you let off the gas, thats when she is dying. I have heard it could be my IACV, my o2 sensor, MAF sensor, MAP sensor, or last but not least, my crank shaft sensor. I was hoping with all the details i listed that someone could advise on a more exact solution. I live quite a ways from EVERYTHING....Autozone is about three miles away,(to have it hooked up to a computer because the CEL is now on!) which i guess isint horribly far, but this car is my first car and im terrified of screwing it up worse. I dont have a lot of money to waste as im a newly single young "kid" (24,thats young,right?!lol) paying my own ways these days! Please, anything you can come up with, i will listen! I dont know what every part under the hood is, but i know a good deal since this poor beast has had to have repairs at home quite a few times! THANKS SO MUCH IN ADVANCE!!! -Kate (southernones@gmail.com)

...........I went to un-plug the battery to see if that helps just enough to get it to a computer....while i was doing that, i took the IAC out, leaving it plugged in. I kicked the car to "on" but didnt start it. As soon as i did, the piston looking thing in the middle of the IAC shot right the heck out! So, im sending my roommate to grab me another one since thats def broke. Im waiting on him to get back to put it in....hopefully that fixes everything. If not, im crossing my fingers and trying to head to Autozone! I will re-post when i find out, and thank you so much for all the ideas!!!!!
